Red Hat Bugzilla – Bug 507217
need an explicit load of netiucv module in ifup-iucv
Last modified: 2014-03-16 23:19:01 EDT
Description of problem:
S390 network devices of type NETIUCV are purely virtual and have no representation on any bus. Hence there is no way of loading the driver module automatically by means of modaliases. Also aliases by means of modprobe.conf are no longer usual, so /etc/sysconfig/network-scripts/ifup-iucv cannot even use the is_available function to load the corresponding device driver.
Version-Release number of selected component (if applicable):
Generate your /etc/sysconfig/network-scripts/ifcfg-iucv0 of choice and the device won't come up (using network service).
/etc/sysconfig/network-scripts/ifup-iucv tries to write to /sys/bus/iucv/drivers/netiucv/connection in order to instantiate such a purely virtual NETIUCV network device. However, the driver module netiucv already needs to have been loaded in order for this sysfs path to exist. Please add a quiet modprobe for netiucv before writing to sysfs and everything will work fine.
This is similar to bug 475721-"[rhel5.3] Alias ctc and iucv interfaces doesn't
work , devices not able to group on-boot" on RHEL 5.
Why not just build it in, then?
Also, last I heard, iucv was deprecated and unsupported in enterprise releases such as RHEL 5; perhaps it should just be removed?
Netiucv is deprecated, yes. Still, users may need it to work as a migration path to some more recent network technology. Building the driver into the kernel seems like a bad idea considering that it's deprecated and that it should only take memory when such devices are really in use.

Opened a new bugzilla to turn off the netiucv device driver in fedora release.
See bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=530577
Setting to MODIFIED.
I took a look at commit "Remove IUCV support" http://git.fedorahosted.org/git/?p=initscripts.git;a=commitdiff;h=9be11466392c3e285571a347b578681ddb3e230a
I wonder why the commit does not remove the references to ifup-iucv in the initscripts.spec?
Because I forgot it. Thanks, good catch.
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.
More information and reason for this action is here:
This landed in F-12 final.
